APPARATUS FOR HEATING AND VENTILATING RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 440,500, dated November11, 1890- Application filed January 10, 1890- Serial No. 336,575- (Nomodel.)

To all whom it may concern.-

Be it known that I, OHALMER M. O. PREN- TICE, of Norwalk, in the countyof Huron and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Heating and Ventilating Railway-Oars; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to improvements in apparatus for heating andventilating railway-cars in which the air-tube or conduct that suppliesthe cars is provided with an enlarged end or hood presenting forward forgathering the air, the air being forced through such conduct by themovement of the train, provision being had for heating the air whennecessary and for supplying air by means of a compressor when the trainis at rest.

In the accompanying drawings, Figure 1 is a side elevation, partly insection. Fig. 2 is a plan in detail. Figs. 3 and 4 are enlarged,respectively, side elevation and plan in detail.

A represents a tube or conduct for conveying air, preferably, from theforward end of the locomotive to the different cars of the train, suchtube having an enlarged end or hood A, preferably funnel-shaped andpresenting forward for gathering the air, the latter being forcedthrough the tube by the movement of the train. lhis tube or conduct maybe of any suitable material, and may lead along the locomotive inposition where it will be most out of the way, usually along the sidesof the locomotive. A branch-pipe A provided with suitable valves, maylead to an air-compressor. (Not shown, but of ordinary construction andlocated where it will be most out of the way.) By means of theair-compressor air is supplied to conduct A when the train is at rest.

B is a heating-coil connected with conduct A, Valve 6 b being arrangedto cut out the heating-coil; but by opening valve 19 b and closing valvea in the tubeA the air is forced through the heating-coil. Theheating-coil may extend into the fire-box or into the steamspace of thelocomotive boiler, whichever may be preferred, according to theconstruction of such boiler. In case, for instance, of. long trains orfor other reasons, if the locomotiveboiler should not be of sufficientcapacity to do the work, a large stove or furnace of suitableconstruction for receiving such heating coil may be located, forinstance, in a car at the rear of the engine.

A small water-pipe 0 leads, for instance, from the water-tank on thetender and discharges into conduct A,-for supplying a spray of water tocool the air in hot weather, and conduct A at the lowest point isprovided with a drip-pipe a, for discharging the water thus introducedinto this conduct. Conduct A is of course provided with a suitablecoupling between the different cars, and at the forward end of eachordinary passenger-car a branch pipe or pipes D leads from conduct Ainto the forward end of the car, pipe D having an elbow presentingrearward and discharging against a double-faced deflector d, byengagement with which the air-current is divided and deflected (more orless) in a lateral direction, so that the passengers along the sides ofthe car will receive the full benefit of such air-current. For sleeping-cars a series of pipes D should lead, respectively, along the sides ofeach berth, the elbows presenting toward the middle of the car, and withor without deflectors, as may be found necessary, according tocircumstances. Each pipe I) is provided with a valve D for regulatingthe air supply. Of course in warm weather the apparatus will be usedonly for ventilating and cooling purposes, in which case theheating-coil will not be used. By taking the airsupply from the forwardend of the engine the air will be comparatively free from dust, smoke,and cinders.

What I claim is 1. The combination, with train of cars, airconductextending lengthwise the train, such conduct having an enlarged end orhood presenting forward and having branch pipes leading into thedifferent cars, of water-pipe connecting with such conduct for sprayingwater into the latter, said conduct being deflected downward and havinga drip-pipe at the lowest point of such downward trend, substantially asset forth.

2. The combination, with a train of cars, of In testimony whereof I signthis specfiicaan air-conduct with branches for supplying tion, in thepresence of two witnesses, this 5th air to the diiferent cars,substantially as indiday of November, 1889.

cated, each branch pipe being provided with CHALMER M. O. PRENTIGE. 5 Vadeflector set in line of such discharge for Witnesses:
